IFL,
You can also see if DW still sells the 7750 powered version of his 6263, I believe those are less than $2,000. I think you can find him on ioffer selling parts/kits.
A lower cost option is to build a VJ23 powered DW 6263 instead, the hour subdial would be frozen (but be sure to use a DW mystery mvmt case for the VJ23, the VJ72 kit has slightly different inner dimensions I understand). I had mine built for under $1200 including a gen T21 crystal and 78350 bracelet, granted that was about 2 years ago. If you get an entire mystery mvmt DW you can use everything except the hands for the VJ23 mvmt, which takes VJ72 hands.
I hope that helps!
Ubi, what impeccable taste you have
